Has condensation formed on
the lens?

environment or if sudden ambient temperature changes occur,
condensation may form on the surface of the lens, and this may cause
the images to appear fuzzy. Set the projector up in the room
approximately one hour before it is to be used. If condensation forms,
disconnect the cable and let the projector stand for a while.
